Barracuda Networks offers a wide range of instructions, tools, and features to maintain your firewall environment, such as update and migration instructions, command-line interface commands and scripts, and system reports for support purposes.
You can update the firewall using the web interface or on the command line. This also works for High Availability clusters.
For more information, see Updating CloudGen Firewalls.
The firewall can be backed up and restored using a PAR file. This file contains all configuration settings. You can also use a USB flash drive to recover your firewall.
For more information, see Backups and Recovery.
